Detta examensarbete omfattar akustiska undersökningar utav en desinficerande diskmaskin av typ Getinge 8666/8668 och har utförts på Getinge Desinfection AB i Växjö. Vi har undersökt hur man med enkla medel kan sänka ljudtrycksnivån i maskinens närhet. Mätningar har utförts på diskmaskinens torkprogram, där torkfläktarna är de mest dominerande ljudkällorna och ljudet främst är luftburet. En systematisk analysmetod bestående av införandet av successiva dämpningsåtgärder visade att de dominerande ljudvägarna går via taket, golvet samt till viss del spalter i maskinens väggar. Genom att isolera både tak, golv och spalter kunde ljudtrycksnivån sänkas med totalt hela 5,9 dB.

Can you ensure that your smoke detector will sense fire and sound the alarm in the middle of the night?In 80 percent of the cases where emergency pulls out, smoke detectors are missing where the fire occurred. In the year of 2009, 118 people in Sweden died in fires ? most of them would have survived if there had been a functioning smoke detector.Earlier development of smoke detectors has mainly been focusing on components that sense smoke and alert in case of fire. But in most cases the problem has not been whether the smoke detector was working or not as fully assembled, but rather that it was missing.

Green roofs have seen a revival in the society of today. They provide many functions of which both society as a whole and the individual can take part. In particular extensive green roofs, that requires little or even zero maintenance, provides very valuable functions. Green roofs affect our environment and our economy in a positive manner as well as the physical expression of buildings. In this bachelor thesis the impact of green roofs on society has been examined throughout literature studies. The result as a compilation of contemporary research in this field is presented together with a discussion about the use of green roofs in general. The two major arguments for an extended use of green roofs are, the high stormwater retention capacity and the cost-benefits seen over time compared to a conventional roof.

This is an analysis of the music in the television-series The Tudors (2007 ? 2010). The opening credits and how death is portrayed musically in the last episode are analyzed. My question is what functions the music has. The method used is Michel Chion?s masking-method.

This project is a learning CD-ROM production aimed at first-time parents. It is using both sound and images, moving as well as non-moving. The purpose of the production is to be an interesting alternative to traditional books. We have been looking at similar productions like drivers license educational CD-ROMs and encyclopedias for inspiration and ideas on how to proceed. In order to give the content some dynamics, we've also added the element of 3D-animated sequences. The application is supposed to be run as a simple executable file with flash embedded.

Extended Producer Responsibility (ERP) is a form of product take-back regulation that requires the producers to manage their products at the end of life. By internalising the products? entire life cycle costs into the market price the ultimate objective of such regulations is to reduce the environmental burden from the products. This Master´s thesis seeks to examine if the total life cycle cost of a product actually is borne by the producer, and if not, predict who will then take this cost. This is done by analysing the market for take-back activities in three different categories of products; electrical and electronic equipment, cars and wind power stations.

In this paper I'm trying to trace, analyze and emphasize Kathy Acker?s Great Expectations and Alison Knowles?s The Big Book in regard to the books in/finite im/possibilities. I analyze them through historical changes in the books format and structure, especially ones proposed by Mallarmé, Duchamp and Fluxus. To analyze the texts more closely attention is directed to how Acker and Knowles challenge the conventional narrative, in regard to the body and language/voice and sound. I give specific emphasizes to thoughts posted by écriture féminine, while also adding Mara Lee?s temporalities in regard to body resistance and time.

Examensarbetet kommer underso?ka aktiv ljuddesign fo?r tysta personbilar. Utifra?n tidigare forskning om hur elbilen utsa?tter ma?nniskor i ta?tomra?den fo?r fara pa? grund av avsaknaden av auditiv information, ska vi utveckla fo?rslag pa? dynamiska billjud som fo?rha?ller sig till trafiksa?kerhet, design och minskade ljudfo?roreningar. Den totala ljudniva?n i sta?der a?r la?ngt o?ver rekommendationen och fo?ljden blir ett ha?lsoproblem i sto?rre sta?der.

Studiens syfte är att belysa några yrkesverksamma elbasisters syn på egen utveckling och dess samband med övning. Som metod har halvstrukturerade intervjuer använts. Informanterna utgörs av tre yrkesverksamma elbasister som berättar om sin syn på övning och utveckling samt vad de anser vara viktigt för att utvecklas som elbasist. Den teoretiska utgångspunkten för denna studie är ett hermeneutiskt perspektiv då målet är att göra en djupare analys och tolkning av de intervjuades livsvärld. Resultatet visar att informanterna tycker att viktiga byggstenar i utvecklingen är att spela tillsammans med andra och lyssna på musik.

The study set out to find how artists organize and use their personal collections from a Personal Information Management (PIM) perspective, and how that use affects their practice and their art production. A secondary object of the study was to articulate the ways that personal collections are utilized as tools by creative users.  The empirical data consisted of five qualitative, semi-structured interviews with Swedish and Norwegian sound artists. The constant comparative method was used for analysis, and Activity Theory was used as a theore- tical framework for the study. The study concluded that artists? personal collections, while diverse in content and structure, serve the same functions as tools in creative processes, and that attention to the uses of personal collections highlight needs that could be better met by integrated PIM-functionality.

While the call for regulations against greenhouse gas emissions are louder then ever before, demand for oil is also at an all time high. Oil companies face the dilemma of making sound business without being perceived as environmental villains. In this essay I will examine how BP, one of the largest companies in the world, broke rank with the industry and devoted itself to being an environmental friendly oil company. The actions and motives of this change will be evaluated through up-to-date theories about company motivation to environmental adaptation. We see that BP:s transformation can be well explained through Simone Pulvers theory about the socially embedded company.

This study examined how users interact with a smartphone while in a learning situation based on videos via smartphones as a learning tool, and how this interaction and phenomena is experienced. The five test subject were separately given the same task that they were to solve using video instructions that were picked out and given to them. After finishing the task the subjects were observed while they demonstrated how they completed the task. After the observation the subject were interviewed using semi-structured interviews. The results show that the user experience of this phenomena is based on more pragmatic values than we could find in earlier studies, i.e.

Noise is a growing health problem. People are not always aware of the injuries that noise can cause. The media culture of today has a big influence on teenagers. This is caused by portable music players, computers, concerts etc. The schools are having larg classes and that can cause a lot irrelevant speech during lessons.

This work is a study in how I as a designer can create the conditions for people to work, socializing and refreshments at one place. A place that encourages creativity, where I made a suggestion at a community table designed for Urban Deli?s new business. By visiting various similar sites I have identified what I think is important in an environment like this and then gave an answer to it in a visual form.A cafe-office will draw lots of different people. Which guests come here to work? Residents, freelancers, but also those who may want surrounded by a new creative work place and maybe leave their regular offices for a day at Urban Deli.
